02
Map
Before testing starts, Sybil builds a model of your application: purpose, tech stack, and full attack surface, authenticated and unauthenticated. You can see this map yourself, so your team knows exactly what's exposed and what's been tested.

03
Attack
A hierarchy of specialized agents tests hypotheses across your applications, each owning a domain like auth, business logic, or injection. The edge is chaining: combining findings into real exploit paths the way a human attacker would.

04
Validate
Every finding passes a multi-stage validation pipeline: deduplication, reproducibility, false-positive triage. Nothing surfaces until it's reproduced independently.

05
Remediate
Each finding includes detailed AI-generated remediation recommendations, plus a "Fix with AI" flow that builds a ready-to-run prompt (or CLI command for Codex, Claude Code, or Cursor) pointing your coding assistant at the RunSybil MCP server to pull finding details and auto-remediate locally. Trigger a retest and an automated validator agent re-runs the original attack to confirm the vulnerability is actually fixed and not just returning a different error. Findings and reports track remediation status end-to-end, so you can see open vs. remediated issues across the full engagement.

06
Continuous
After the initial engagement, Sybil tests only what changed, triggered by a PR, a manual run, or a set cadence, informed by everything it already knows about your application. That's what makes ongoing coverage viable at scale, instead of a scanner re-running blindly on a timer.



An AI scanner can't tell you what it didn't test. Sybil can. Ask "did you try this?" at the finding level, and get an answer.

Sybil tests your web and API attack surface — authenticated functionality, access control, business logic, injection, multi-tenant isolation, and novel bugs — mapped as connected exploit chains rather than isolated findings.
Every finding passes a multi-agent validation pipeline: a critique pass, a reproducibility check on a clean session, a dedicated false-positive triage agent, and duplicate detection. Anything that doesn't survive every stage gets dropped.
Engagements start the same day you onboard. Smaller applications complete same-day; large, complex applications take up to 24 hours. Retests complete in under an hour, with no scheduling required.
Yes. RunSybil customers have satisfied SOC 2 Type II and ISO 27001 audits using Sybil's output, which ships pre-formatted with CVSS 3.1 scores and CWE IDs.
